Help Us Save The Great South Bay
For future generations
It’s our bay, our heritage — and our legacy. We grew up clamming it, sailing it, swimming in it. Now our bay is sick, and we must heal it, for today and for the future!
Save The Great South Bay is a local 501(c)3 non-profit that actively works to restore the bay, and with that, strengthen our South Shore communities.
